shaped by collars on the horizontal rolls'. This rolleonstrnetionenables any fins formed on the edges of the langes to be' rolled downloy reversing the bar, or ro` Y rating it through an angle of 18.0,between successive passes through the rolls, as fully sel. 'forth in myprior application, Ser. No. 355,380, 'iledu June 2, 1908. Each verticalroll is supporled and adjusted by a chock8 which 'slides horizontally inguideways 9 .machined in brackets 10 cast integral with-65 andprojecting outward from a housing l. 5.

Means are provided for simultaneously adjusting the horizontal rolls,and also, preferably, the Vertical rolls, so as to accuialcly niainlainthe shape of the pass. Various mechanismsmay be used to eiliect thissimulhineons adjustment. That shown eoinf prises vertical screws l1which pass through nuls fixed in the upper and lower closed einlioi ellehousings 1., and bear against the journal-boxes 3. A bevel-gear 12 ,uiskeyed on the onier end of each screw, the@ gears engaging complementarygears 1b keyed on upper and lower horizonlal shafls 1 lll. Alinedsprockets 15- connected by ijn 80. ohain- 'lll are alsokoyed on theseshaftgso that they rotate in unison, thereby causing the simultaneousand equal inward movement or' the horizontal rolls. Pairsof horizontalscrews 1T are threaded Athrfmgh'cross 85 plates 10 which are bolted tothe outer, ends of the brackcls 10. 'These horizontal .screws also carrySprockets 18 and are preferably rol'n'ted in unison with tliererticalscrews 11, die sprockel's 18 at the Aright engaging'Q che chain 1G whilethose at the left engage a chain 19 which is driven loy a sprocket 2O onthe upper shaft lfl. The screws 17 bear againsttbe onler ends oi thechooks 8- and thereby force the vertical rolls inward simultaiiconslywilli the horizontal rolls, through a dislance which predetermined bythe pitch of the screws., so as to maintain the exact shape ol the passThe distance between the housings 1 may be adjusted lo sull di'llcrenlrolls by moans ofthe ric-bolts 2l whichconnecll the cr0ss- 4 plates l0.v

Suitable guides for the blank' may be' allached to the bolts 21 andtothe honsings.
